Re: problem with Delta GPS750AB A PSU. No +5v VSB
TNY280PN datasheet:
https://cdn.badcaps-static.com/pdfs/...953d6e2eb9.pdf
R1 was 4.33K +5vsb unstable
replaced with 1K 5V stable, but when soldered back supervisor IC and other smaller board, instantly burned.
It's hard to tell what original resistor was as it overheated (was coated all in resin) the color code read as 4.33K
